🎮 Building a DIY Gaming Console Using ESP32
Retro games never get old.
As makers and embedded developers, we usually build IoT dashboards, sensor projects, automation systems, and robots. But this time I wanted to build something different:
A mini gaming console powered by ESP32.
The goal was simple:
✔ Build with low-cost components
✔ Add multiple games
✔ Use an OLED display
✔ Keep it open source
✔ Make it easy for anyone to recreate
The result is a compact DIY gaming console capable of running classic games directly from an ESP32 development board.
